I understand that the period of assistance is from Aug. 1, 2020 through Dec. 27, 2020, but how much funding within the Period of Assistance did FEMA approve?

The start date for both the Period of Assistance and the Period of Performance is July 25, 2020, which is the start of the week ending Aug.1, 2020. FEMA approved six full weeks of funding for Lost Wages Assistance from the week ending Aug. 1, 2020, through the week ending Sept. 5, 2020.
